Application filed January 27, 1913. Serial No. 744,496.

'1 o a whom it may concern lie it known that I, FREDERICK E. Km'xnnn, a citizen of the. United States, rcsidiug at Canon City, in the county of Fremont and State of Colorado, have invented certain new and useful Improvements in (lo1icrete-Distributers; and I do declare the :tollowing to he a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it up pertains to make and use the same.

This invention relates to endless conrevers, and more especially to those employing a trough, chains moving along the same, and a peculiar form of bucket attached to the chains and traveling in the trough; and theobject of the same is to produce a concrete distributer for attachment to a concl'ete mixing machine which is moved along the street, the distributor swinging from side to side to eliver the mixed concrete over the surface as may be desired.

This and other objects are carried out by constructing the machine in the manner hereinafter more fully described and claimed, and as shown in the drawings wherein Figure 1 is a side elevation and Fig. 2 a central longitudinal sectional view of this machine complete. Fig. 3 is a plan view thereof, Fig. i a cross action on the line 44 of Fig. 3: Fig. 5 an enlarged cross sectional detail of the gear ring hereinafter referred to. Fig. 6 is a perspective detail of one of the blade-supporting bars.

In the drawings the numeral 1 designates the framework and 2 the platform of any suitable machine such as a concrete mixer whose details of construction it is not necessary to illustrate as they form no part of the present invention, and 3, 3, are uprights risingfrom said platform near its rear end and connected by a top bar 4 carrying an eye bolt 5. Attached to the latter is a chain 6 whose outer end is connected with an eye 7 atthe center of a bail 8 which supports the outer rear end of the carrier hereinafter described, and it is obvious that by shortening or lengthening this chain the outer. end of the carrier may be raised or lowered as is necessary while the support therefor is such that said outer end is permitted to swing from side to side in the act of delivering the mixed concrete or other material. 'The'plat form is provided with a large opening-9 within which stands a two-part gear rlng as l best seen in Fig. 5. This comprises an upper member 10 having a ball race 11 in its lower face. a peripheral ring of teeth 12 rismg from its upper face, and a shoulder 13 depending from its lower face inside said rare l1 and around its central opening 14: and a lower member 15 having a peripheral ringof teeth 16 in its lower face and a central opening 17 of a size to register with that numbered 14. The two members are con nected by means of bolts or screws 18 (Fig. I '2) which pass through holes 19 in the upper member 10 and into threaded sockets 90 in the lower member 15 and hold the two members together. so that the shoulder 13 forms the bottom of an annular groove around this element. Said groove receives a large ring or turn table 21 which rests upon the platform 2 around the opening therein and which has a ball race 22 registering with that in the lower side of the upper member 10 so as to receive balls 23 by means of which the gear ring is supported upon said ring 21' while the latter in turn is supported by the platform. The construction is such that the gear ring may revolve very easily upon the ball bearing (or other bearing if one of some other kind is employed) by means of which it is supported by the turn table. and the latter may rotate upon the platform when the carrier is swung from side to side as described below.

Depending from the ring 21 at diametrically opposite points are two hangers 25 in which are journaled the outer extremities of stub shafts 26 standing in alinement and projecting from opposite sides of a semi-circular trough 27, formed preferably of sheet steel and having flat flanges 28 along its edges. Secured to and depending obliquely from and beyond both ends of this trough are metal straps 28 which have bearings for cross shafts 29 carrying sprocket wheels 30 at their extremities, and around these sprockets more two sprocket chains 31. One of said shafts (herein the outermost) carries a sprocket wheel 32 connected by a chain belt 33 with another sprocket wheel 34 Whose hub journaled on one of said stub shafts-26. and the outer end of this hub carries a beveled gear 36 meshing with the teeth 16 in the lower member 15 of said gear ring. The

in the present instance Ihave shown a power cearfi'? meshing with the teeth 12 in the upper member 10, said'gear being mounted on latter is rotated by any suitable means, but. i

a short shaft 38 journaled in a bearing 39 on the platform and having a sprocket wheel 40 at its outer end driven by a chain belt 41 which is led from any suitable source of power. It will be clear, from this description, that power imparted from the gear 37- rial along the trough 7 I mount buckets or blades on the chain 31 in the manner best shown in Fig. 6. That is to say, each bucket or blade 42 is a semi-circular sheet of metal whose Straight edge is bent at right angles to its body into a lip 43, and across the lip is secured a flat metal bar 44 having fingers 45 near its extremities projecting at right angles to its body and adapted to slide along the flat upper faces of the flanges 28 of the trough as best seen in Fig. 3. The ends of this bar 44 are riveted as at 46 to the shanks of T-shaped connectin r members 47 whose heads in turn are attac ed to opposite links in the two chains 31. With this specific construction, it follows that as the chains travel in the direction ofthe arrows shown-in Figs. 2 and 3, the fingers 4:) precede the bars 44 and slide along the flanges 28 of the trough 27 so that said he rs are caused to stand flat, and as the lips 43 at the upper ends of the blades 42 stand at right angles to their bodies, said bodies are caused to stand ver tical so that the material within the trough is pushed alon as indicated in Fig. 2. By this means I re ieve the chains of the burden of holding said blades upright, and that burden is borne by the flat edges of the trough; and I consider this detail of construction important in a machine of this character, as the burden is considerable when the volume of material is large.

- With the machine constructed as above described, its operation is as follows: The material to be delivered by this distributer or conveyer will doubtless be mixed concrete which it is intended to spread over the full width of a street being paved. As above suggested, the concrete is mixed in any suit-. able manner forming no part of the present invention, and from the mixing machine it is passed through a spout into a hopper 75 which may well be mounted upon the gear ring as seen in Fig. 4. Falling through this hopperand ring, it 1s dropped into the trough 27 near the inner end of the latter, and therein it is moved positively outward gers depending by the blades which travel in the direction of the arrows. The outer or delivery end of the conveyer may be raised and lowered by shortening or lengthening the chain or other support 6, and it is obvious that it may be swung fro-m side to side by hand or by suitable machinery forming no part of the present invention. Its inner end is sup ported on the stub shafts by the hangers 25 1 from the ring or turn table 21, and the latter is mounted movably on the platform 2. The proportions and materials of parts are not essential to the successful operation of this invention.

What is claimed as new is r 1. In a machine of the character described, the combination with a platform having an opening, a ring mounted on the platform concentric with said opening, hanfrom said ring through the opening, a conveyer having stub shafts near its inner end journaled in said hangers, and means for supporting the outer end of the conveyer; of a two-part gear whereof the uppermelnber overlies said ring and has a shoulder projecting through it and the lower member underlies such'ring, said gear being open for the passage of materlal therethrough, driving mechanism for said conveyer including a beveled gear, teeth on said lower member engaging such beveled gear, and means for rotating said two-part gear.

2. In a machine of the character described, the combination with a platform having an opening, a ring mounted on the platform over said opening, hangers depending from said ringthrough the opening, and a conveyer having stub shafts mounted in said hangers; of a two-part gear whereof the upper member overlies said ring and has a shoulder projecting through it and the lower member underlies such ring, said gear being open for the passage of material therethrough, a wheel whose hub is 'journaled on one of said stub shafts, a

beveled gear fast on said hub, teeth on said lower gear memberengaging this beveled gear, connections between said wheel and conveyer for moving the latter, teeth on said upper gear-member, and a power shaft mounted on the platform and carrying a gear meshing with said gear teeth on the upper member, for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
